Well I’ve made reference to this gun before as my “LAW” or my coaxial air cannon; I figured I might as well post it.
It was never finished, meeting an untimely demise at the hands of gravity (it fell of the loading bench well I was doing some test fires last week.), but here are some of the original pictures and the guns specs:

Caliber: 1.50 inch
Barrel length: 28 inches
Camber diameter: 3 inches
Chamber length: 28 inches
Muzzle velocity with a 3oz. projectile: approx. 300FPS
Max arming range: approx. 300 yards
Max combat range: approx. 150 yards
Accurate range: approx. 100yards
Min arming range: approx. 30 yards

The piston was made out of hot glue, works great, and the sealing face is sheet rubber labeled as “gasket material”.
The muzzle end has a built in coupler and the plan was to modify that and a short piece of pipe so that the barrel could easily be extended for longer ranges.
Originally it had a 0-100psi gauge on it but I upgraded it to a 0-150psi gauge.
Later on I added a ball valve safety, and some decals.
When I get around to fixing it I’ll paint on the decals and put a brass plate on the butt-stock with the make and model on it.

And here she is:

Bazooka It is a portrait of sweetness. I approve.

thats awesome. shame it got damaged. what was the smart thing we wouldn't get?

Great job!
Love the bazoola look and the carved wooden shoulder stock, along with the front handle. I vote you should mount a scope off the side, it'll be even awesomer (is that a word? hmmmm).

Yes, what is this smart thing we wouldn't get?

Yeah thanks, I was going for the Bazooka look, except shorter.

you didn't get it? it's a joke I got it off a T-shirt at the China-Mart...


I forgot to say this in my original post:
The gun was designed to be portable; it’s about the length of a gun case so it fits in the back of our van. Oh and here are the decals I made for the cannon:

See that's what happens when you learn your jokes at the China-mart. If you would have learned that same joke at Wal-mart we might have got it. But no, you had to go all asian on us.

it was so simple i thought i was missing something lol.

Yea, I'll agree. Normally I breath sarcasm but it's been a really long day. Oh yea, I'd just like to take this chance to tell everyone that I hope you had a good Singles Awareness Day today.

People post to fast… Can’t keep up…

No scope, I am going to make an optical sight though, just no magnification. The magnification makes it hard for me to judge distance.

The wood was fun to work with, but it doesn’t fit right, that's another thing that needs fixed.

I’ll post pics of the gun in it’s current, damaged, state as soon as posible.

You know what would make it look lieka real bazooka when you shot it? If you put some powdered magnesium behind the projectile. That'd make for a sweet muzzle flash.

Except that's it's kind of a PNEUMATIC.

Jeez, I deleted the topic reply notification Email and another took its place 10 seconds later....

Aw, friggin crap. My bad, I was thinkin combustion. Thats what I get for jumping from forum to forum. Well. I guess you could always put little sparklies behind the potato and it'd kinda give you a muzzle flash-ish kinda type thing...

Very nice cannon. So you sleeved the 3" chamber in 4" pipe?

very sweet you need to fix it and get it working.
